SCRIPT EXISTS

Original Source

Returns information about the existence of the scripts in the script cache.

This command accepts one or more SHA1 digests and returns a list of ones or zeros to signal if the scripts are already defined or not inside the script cache. This can be useful before a pipelining operation to ensure that scripts are loaded (and if not, to load them using [SCRIPT LOAD]({{< relref "/commands/script-load" >}})) so that the pipelining operation can be performed solely using [EVALSHA]({{< relref "/commands/evalsha" >}}) instead of [EVAL]({{< relref "/commands/eval" >}}) to save bandwidth.

For more information about [EVAL]({{< relref "/commands/eval" >}}) scripts please refer to [Introduction to Eval Scripts]({{< relref "/develop/programmability/eval-intro" >}}).
